generally unused, as it is incompatible with the Tcl/Tk build of
magic. However, I had not intended to remove it, only move the
name from "readline-4.3" to "readline". But "readline/readline"
was in .gitignore, which caused the contents to be removed from
the repository. This commit restores those files, and also
prevents the readline directory Makefile from making a symbolic
link called "readline" to itself, which was causing compile-time
issues. The readline code is only kept for backwards compatibility
with ancient versions of magic not using the Tcl/Tk interpreter.
and incorrect call to cairo_set_source_rgba which is in an unused
function and has no effect except with versions of Tcl less than 8.6
where "load -lazy" is not available and unknown functions cause
immediate exit. Cleaned up remaining references to OpenGL in the
Cairo code, and updated the copyright and acknowledged Chuan Chen, who
coded the Cairo interface. No attempt yet to deal with memory leaks
caused by calling Cairo "create" functions without the accompanying
"destroy" functions.
the python preprocessor version, the techfiles and .magicrc file
will get the correct arguments, without affecting the use of CPP
in the configure script.
